- ings occur at once, everything being. simul" taneous. My totalizer, which operatesin this last-mentioned manner, possesses a greatadvantage of speed, and the amginm'ent of. speed is one of the objects of my invention. Y

Another object of myirfi'ention is to pro-- duce a reversible totalizer which may operate for both addition and subtraction, and it may be interesting from a" theoretical standpoint to mention that m y presentmechanism may even be made-to add in some decimal places and simultaneously subtract in other decimal,

. places. .Th'us it may simultaneously add in the unitszmlllmmdbtract in the tens-column add in the hundreds and t ousands columns.- -&c.; although such use would probably have no commercial application. I Another of the objects of my invention is to make .the mechanism of the to'talizerselfcontained, so thatino'. auxiliary mechanism is" required to. reset its'parts to normal or.

nitial position after each accumulation or totalizatiop. In consequencea long column of many numbers, each number composed of many figures, may-be run into the 'totalizer without waiting for any pause or break be-' tween the various numbers, andit b'ecomes immaterial whether the accumulations take I place first in the units-place, then in the tense place, &c., or in the reverse order orall together or inany' other orden.-

I accomplish my object by the mechanism illustrated in the accompanying drawings, in

" taken on line?) 3, Fig. 1.

. are side views of component parts-of the mechanism. Fig.8 is a sectional view of the initermediate wheel-located farthest to the right. This wheel is non-rotatable and is shown to be pinned to the axle, whereas'the intermediate wheels to the left thereofare rotatable.

Similar reference characters denote similar parts" throughout the several views.

The device in the form here shown comprises the non-rotative shaft 1 and a plurality of sets or groups consisting of five principal partsnamely, the totalizing-wheels 2, the carrying-pinions 3, the accumulating-wheels 4, the epicyclic pinions 5, and the intermediate wheels 6. Wheels 2, 4, and 6 are all freely rotatable on shaft 1 independently thereof,

- with'the exception of wheel 6, located 'at the extreme right to correspondwith the unitscolumn. This wheel is rigidly fastened to said shaft by means of a pin 6", (shown in Fig. 8,) although any other means maylbe substituted for holding it rigid and non-rotatable.

The function of said wheel 6 is to form the r ,fixed basis of reference or foundation piece of the mechanism from which the rotatable parts move their definite amounts.

In each group of parts, 1 represents asupporting-piece, which in the present-instance iis disk-like in form and issecured to shaft 1 byineans 'of a spline 1",althou-ghsaid supporting piece may be held rigid upon the shaft by any other suitable means. Said supporti'ng-piece is provided at its left side with a hub 1, which is cylindrical and fo ms a bearing whereon theintermediate wheel 6 is'freely rotatable. The pin 1 extends to'wardthe left from said supporting-piece 1- and serves as. an axle whereon the carrying-pinion 3" is freely-rotatable. Said pinion has eight long and -short teeth alternatingwith'each other .for alternately being locked and rotatedby the totalizing-wheels 2 in'the manner hereinafter described.

The totalizing-wheels '2 carry oii their "cylindrical-peripheries two series of'figures for visibly indicating the numbers set up, as-usnal in mechanisms ofthis class. Each series of figures runs from 0 to 9, thus making twenty figures, which are consequently onetwentieth of a circumference .apart. Said wheels have formed upon their left portion an internal forty-toothed gear 2, as best shown in Figs. 2 and 4., and to the left of said gear portion 2 is an internal cylindrical surface 2 for locking the carrying-pinion 3, which conhas two slots or spaces 2 located diametrically opposite to each other, each slot having a projecting carrying-tooth 2* on each side thereof for engaging the teeth on said carry- 'whcel is an internal cylindrical surface or ring 2, which is of greater diameter than r'ing 2 and is cut in the wheel for the purpose of clearing the short teeth onsaid carryingpinion.

1 The construction is such that the carryingteeth 2 of the wheel 2 will engage the short teeth of pinion 3 and'rotate the same two steps. or tooth-spaces, after which the locking-ring 2 will enter between two adjacent long teeth on the pinion 3 and lock the same.

Dufing the rotation of the locking-pinion the space 2 wi l permit the rotation of the carstitutesa'locking-ring. Each totalizing-wheel rying-pinion by receiving one of the long teeth thereof. Thus when the totalizingwheel 2 is rotated it will twice during-each complete rotation impart a partial rotary movement toits carrying-pinion to carrythe tens. Although in the present construction the totalizing-wheel 2 carries at two points and h as two sets of figures, the fact that it is dou-' d that.

the reason that this number. afiords. security in the locking action. With this construction .bnly four long teeth occur, and consequently.

there is a wide angle between their adjacent faces to wit, almost ninety degreesthereby affording a large space for the reception of the locking portion of the totalizing-wheel.

It willbe noted that the totalizingrwheels "perform three distinct functions: First, -,they

constitute figure-wheels; second, they act as carrying-wheels. for alternately rotating and act as totalizing-'wheels'that is, they. receive rotation both. from the accumulating-wheels locking the carrying-pinions, and,.third, they- "and the tens-carrying means, and they alge'-' an internally-toothed totalizing-wheel freely -braica'llycoinbi gortotalize the two effects;
